I can also combine the two (12+ of each) in the same shipment for $17 shipping included if you'd rather have them both.

If you are interested in more eggs I can do 18+ and 24+ for buttons or 18+ for coturnix.
18+ buttons is $15 shipped
24+ buttons is $18 shipped
18+ coturnix is calculated shipping (heavier box) plus $5 for the eggs.

In coturnix I have a pair of whites (m/f), a trio of cinnamon (1 female, 2 male), a tuxedo male, a rosetta male, 4 rosetta and tibetan females, 2 brown females, and 2 golden females. Currently they are all in the same pen.
